GAR CONSTRUCTION Filed July 27, 1928 Patented Apr'. 22, 1930 `UNITED TOI-IINA F. OCONNOR, OF CHICAGO, ELLINOIS, ASSIGNOR T0 VJ, H. MINER, INC., OF CHICAGO, ILLNOIS, A CORPORATION OF DELAWARE CAR CONSTRUCTION .Application led July 27,

This invention relates to improvements in car construction. V

One object of the invention is to provide means for connecting the body and truck bolsters of a railway car, including a sectional center pin member composed of a plurality of plate-like elements having shouldered engagement at opposite ends with the body and truck holsters, respectively.

Another object of the invention is to provide a center locking pin arrangement for body and truck holsters having center pin receiving openings, wherein the connecting pin comprises a plurality of plate-like sections which may be readily attached to or removed from the holsters, as desired, the plate-like sections being adapted to be assembled in succession with the holsters and forming, when assembled, a complete pin member, headed at opposite ends, having shouldered engagement with the holsters to prevent separation of the same, the openings in the holsters being of such a shape asy to permit insertion of the plate-like members in one position, the plate.n like members being rotatable about the axis of the assembled pin to bring all of the sections thereof into shouldered engagement with the holsters, locking means being provided to prevent relative rotation of the assembled pin and one of the holsters to hold said sections against disengagement from the shoulders of the holsters.

Other and furtherobjects of the invention will more clearly appear from the description 35 and claims hereinafter following. A

In the drawing, forming a part of this specification, Figure 1 is a vertical sectional view through the body and truck holsters of a railwL y car, illustrating my improvements in connection therewith. Figure 2 is a top plan view at the central portion of the structureshown in Figure 1. Figure 3 is a bottom plan View of the construction illustrated in Figure 1, at the central portion of the truck bolster. And Figure 4: is a detailed perspective view of one of the plate members forming a section of the center locking pin of my improved construction. f

In said drawings, 10 indicates a portion of the body bolster of a railway car and 11 a 192s. serial No. 295,655.

portion of the cooperating truck bolster. The body holster is provided with a hollow, sleevelike section 12 which receives the upper portion of the locking center pin and a depending annular hearing member 13 cooperating 5 with an annular bearing seat 14 formed in a hearing plate 15 seated in a pocket 16 at the top of the truck bolster 11, a filler or shim member 17 being interposed between the hearing plate 15 and the top of the bolster 11. The bolster 11 is provided with a. center pin receiving opening 18 and the hearing plate 15 and shim member 17 are also provided with openings aligned with the opening 18 and the opening of the sleeve section 12 of the body bolster. v

In carrying 'out my invention, I employ a sectional center locking pin A, composed of four heavy plate-like members 19-19 and 20-20, which, when assembled, form the com- 7c plete locking pin; a pair of locking blocks B-B; and a cottcr pin C for locking the blocks B-B to the sectional pin A. l further form the center pin receiving openings of the bolster o-f such a cross section as to facilitate the entering of the sections of the pin A. 1 1

The four sectional plate-like members 1.9-19 and 20-20 of the pin are of similar design, but the plate-like members 20 are ot' greater width than the members 19. Each plate-like member comprises a` main body portion of substantially rectangular cross section which is elongated so as to form a shank portion of the pin. At the opposite ends, each plate is provided with a paiizof aligned laterally projecting lugs 21-21, the lugs at each end forming in effect a head portion. As shown in Figure 1, the head portions 21 at the upper ends of the plate members cooperate with the flat end face of the sleeve-like section of the bolster 10, thereby supporting the assembled members which form the center locking pin A against downward movement. The head portions 21 at the opposite ends of the plate cooperate with the bottom face of the middle section of the truck bolster in a similar manner so as to prevent upward movement of the pin and hold the same assembled `with the body and truck holsters and lock the holsters together.

As clearly illustrated in Figure l, the aligned center pin receiving openings of the body and truck holsters are of the same diameter and each opening has the side wall at diametrically opposite portions slotted, as i' dicated at 22-22. The slots or openings are of such a Width as to permit the head sections 2l of the plate .members 20 to pass freely therethrough in assembling tnev plate members with the holsters. As most clearly illustrated in Figures 2 and 3, the slots 29 are to one side of the diametrical center plane of the pin receiving openings of the holsters.

. As herona' ter more clearly pointed out, the slots Q2 are offset to one side of the center of the openings in therbolsters to facilitate insertion of the plate member 20, which is last applied in assembling the pin and which plate member in effect forms a key plate.

The two locking blocks B are provided to preventrotation of the sectional locking pin A after theparts thereof have been assembled and the pin is in the position shown in the drawings. Eaclrlocking block comprises a bottom section having a flat inner face Which abats the outer side of one of the plates `19 and a curved face on the outer side which fits the curved side Wall of the pin receiving opening of the sleeve l2. Each block B is also provided Withf an outwardly Vprojecting lug member 23, adapted to fit Within the slot22at the corresponding side of the pin receiving opening of the sleeve l2. Each hloclris also provided With an upstanding section provided with a Cotter pin receiving opening 25. VEach of the platemembers formingthe sectional center Ylocking pin A is also provided Witha cotter pin receiving opening 26 at the upper end thereof; hen thesectional locking pin A is assembled and disposed in the position shown in Figuresl, 'z2 and 3, and the blocks have been inserted iii thepin receiving opening of the sleeve lQrat oppositersides of the sectional pin A with the lugs 23 of the locking blocks engaged ivithin the slots 22, the lool;- ing blocks are secured to the sectional pin A by means of the cotter pin C, Which is inserted through the aligned openings 25 of the lool:- ing blocks and 26 of the plate members. As will he evident, the locking blocks are thus secured to the sectional pin A and rotation of the pin is prevented hy the locking blocks which have the'l lugs thereof interlocked with the slots 22of the sleeve l2.

4 In assembling the parts of my improved sectional center locking pin to connect the holsters, the parts of the same are in the present instance inserted through the upper end of the sleeve section l2 of the body bolster, inasmuch ,the invention is illustrated in connectionyvith body and truck holsters associated with the six-Wheel type of truck, the central axle of which is shown in dotted lines beneath the truck holst r ll and is designated by 27. As Will he evident With the axle member 27 located immediately helov7 the central portion of the truck bolster and in vertical alignment with the center locking pin receiving openings of the holsters, it is not possible to insert the pin sections 'through the bottom of the opening in the truck bolster'. However, it Will be obvious that When my improved center pin arrangement. is employed in connection With the holsters of a car provided With other than six-Wheel trucks, the parts of the pin may he inserted through the bottom end of the pin receiving opening in the truck bolster and the locking blocks may be associated With Vthe last named bolster. ln applying the sectional center locking pin A to the holsters l0 and il, one of the narrower sections 19 is first applied. by inserting the saine Within the opening of. the sleeve l2 through the upper end of the sleeve,.iirst bringing the lucs 2l of the section in alignment With the slots 22 of the center pin receiving openings of the holsters. After the bottom lugs 2l of the plate 19 referred to have been passed through the center pin receivingl openings of the holsters, the plate is displaced to oneside ofthe slots 22 so as to overlap the lugs 2l at the-opposite ends of the plate with the abutment facesof the body and truck holsters. l

. The second ,plate 19 is then applied in a similar manner and displaced laterally so as to dispose Athe plate on the opposite side ofthe pinr receiving opening lto that occupied by the plate 19 first inserted. @ne of the Wider platesQO is then inserted in a similar manner and displaced to one side of the slots 22, thus leaving the slots open to permit inser. tion of the last plate forming the sectional center locking pin. The last plate 20, which in effect forms the `key plate to hold the remaining plates separated and the pin in 'assembled relation, is then inserted in the pin receiving openings in the same manner as the other l plate members, and after the lugs 21-2l at the lovver end, of the key plate have been brought in alignment with the lugs 21-21 at the bottom end of the remaining plates the assembled sectional center looking pin A is rotated bodily through an angle of ninety degrees, thereby bringing the same into-the position shown in Figures l, 2 and 3. As Will he evident- When the sectional locking pin A is thus positioned, all of the plate menihers thereof have shouldered engagement With the abutmentgfaces on the body and truck holsters thereby preventing separation of the holsters under all conditions.

To lock the sectional pin A in position so that the same Will not rotate with respect to one of the holsters, t-he tvvo locking blocks B are applied to opposite sides of the assembled loclting pin and the lugs 23 of the looling hloclrs engaged Within the slots 22 of the sleeve l2 of the bolster 10, as hereinbefore pointed out. rIhe locking blocks are then secured to the plate members forming the sectional pin by the cotter pin C.

Vhen it is desired to remove the sectional locking pin so that the holsters may be separated, it is merely necessary to irst remove the locking blocks B and then rotate the locking pin A through an angle of ninety degrees to bring one of the plates 20 in alignment with the slots 22. rllhe plate 20 may then be driven out and the remaining plates displaced laterally so as to bring the same in alignment with the slots 22 and the latter may then he driven out in a similar manner.
